Ministry of Land, Infrastructure and Transport(MOLIT) has increased reduction rate from 18.1% to 32.7% in Building sector compared to BAU of the national greenhouse gas emission according to the 2030 Greenhouse Gas Reduction Road map Amendment. For this purpose, MOLIT has been activating the green remodeling projects for existing buildings. Considering that 15 year old buildings after completion are 74% (5.25 million buildings) among about 7 million existing building stocks in Korea, reduction of building energy consumption by green remodeling is urgently needed, However, it is a major difficulty of activation for green remodeling projects because there are few case studies on Before and After building energy consumption of actual green remodeling projects. Considering that building energy performance and value increase after green remodeling through previous researches, additional studies of the energy consumption assessment on actual green remodeling projects are essential. Therefore, this study aims to propose results on Before and After building energy consumption of actual green remodeling projects.

In this study, we analyzed reductions in heating costs in remodeled apartments in terms of maintenance fees due to the difficulty in quantitatively assessing the effects of remodeling in aging apartment buildings. A comparison of the heating energy consumption of a subject apartment before and after remodeling showed a reduction of approximately 66.8% per unit area. After accounting for an increase in the floor area due to expansion, the reduction per household was approximately 57.8%. An analysis of the proportion of heating costs within total management fees revealed a decrease of approximately 57.5% after the remodeling. A simulation review using the Zero Energy Building (ZEB) certification system revealed that the remodeled building’s primary energy consumption was 119.0 kWh/m², which achieved ZEB Grade 5 with an energy self-sufficiency rate of 20.94%. These findings confirm that remodeled apartment buildings provide a favorable environment for achieving energy self-sufficiency through rooftop photovoltaic installation.

국내 소비 에너지 사용량의 97%를 수입에 의존하고 있고, 지구온난화와 관련된 환경문제가 심각하게 대두되고 있는 실정이다. 또한 우리나라 에너지 부문별 소비형태에서 47%를 차지하는 산업용의 에너지 소비는 대부분 유류에 의존하고 있고, 그 중에서도 제조부분의 소비가 91.5%로 나타나고 있어, 이 부분에 대체에너지원의 개발, 대체 시스템의 적용이 절실히 요구되고 있다.<br/> 우리나라에서도 국가적 에너지 절약과 쾌적한 주거환경 및 생활의 편리함을 위해 기존 화석에너지로부터 무공해 청정에너지(Clean Energy)로 그 사용형태가 바뀌어 가는 지금 그 양과 질적인 면에서 무한정이고 무공해인 대체 에너지원으로서의 태양에너지는 다양한 이용분야가 개발되어 실용화되고 있다. 국내의 경우 대표적으로 평판형 태양열집열기를 이용한 온수급탕 시스템을 들 수 있고, 냉난방, 산업공정열 및 태양열 발전 분야에 대한 실용화 및 타당성 연구가 활발히 진행되고 있다.<br/> 따라서 본 고에서는 태양열 시스템의 중요한 구성요소인 고효율 집열기술에서 산업용 응용(70~150℃)에 적합한 것으로 기대되는 진공유리관형 태양열집열기, 국내·외 기술개발 동향과 산업공정열의 대체 가능성에 대하여 기술하였다. Solar energy is a quantitatively unlimited, clean and non-pollutant source. It has a great potential for industrial commercial usages. For example, solar hot water system for domestic usage has been very popular in many counties.<br/> In Korea, the industries consume 47.7% of the total national energy, and the manufacturing sector uses 91.5% out of it. The main energy resoures available in Korea are oils, coals, and gases. There have been continuous efforts among the industries to reduce such energy consumptions by using alternative energy resources, such as solar energy, yet the technology has limited its proper applications to a level of satisfaction. In some advanced countries, research and development programs in solar energy applicable to the industrial usages are very active, and some systems are in the commercial market.<br/> Therefore, this paper describes the status and the feasibility for high-efficiency evacuated solar collector which was anticipated to applied for industrial process heat as an alternative of fossil energy.

This study developed a KRESS program designed to find the optimization ratio for new and renewable energy systems and analyze the effects of building energy consumption characteristics on the ratio. In spite of clear differences in predicted energy consumption and energy consumption by the loads among 18 facilities, the current formula for obligatory supply ratios applies a correction coefficient according to the building purposes based on energy consumption per each unit area in medical facilities and thus reflects no energy consumption characteristics according to the building purposes. The optimization ratio for new and renewable energy systems was the same for all facilities when the correction coefficients by the building purposes and new and renewable energy sources were all applied. When the correction coefficients were not applied, however, the optimization ratio varied according to building energy consumption characteristics. The findings raise a need to test the correction coefficients in order to select new and renewable energy systems that take into account energy consumption characteristics by the building purposes and loads and reflect economy, environmental performance, and technology.

Recently, many sociaL economical and political problems have occurred in the field of urban energy supply because of the depletion of fossil fuels and the international climate change agreements and the current energy-related laws focus on individual buildings which makes them difficult to implement. Also, the policies for energy savings have increased day by day, but it is difficult to establish efficient urban plan because of lack of integrated policies and institutions. Current legal systems for urban plan does not cover domestic and intemational climate change agreements, energy related industry's structural changes and other environmental problems such as embodied energy and global warming. This paper tries to investigate current conditions of legal system to provide fundamental materials for improving energy conservation in urban plan.

Apartment balcony has been remodeled since the government permitted remodeling in January 2006. But extended balcony has great impact on building heat gain and loss. Therefore It has problems such as increase of heating and cooling energy. So technical solutions about window solar gain in summer is an urgent matter. The Purpose of this study is to evaluate energy performance of a blind in a double-skin facade in residential buildings by using Energy Plus program. The results show that slat angles of 90° is best in energy performance if we do not consider daylight. Poorly daylighted living room needs electric light and it also causes high cooling load. On the other hand, the results show that the application of blinds controlled automatically is best for energy performance when we consider daylight. Blind slat angles of 50∼60° have best performance when blinds are controlled in this angle throughout the day on a clear day in August. Blind slat angles of 0∼30° have best performance when blinds are controlled in this angle throughout the day on a cloudy day (more than 7 of total sky cover) in August.
